To: all-,whom it may concern:

Be it known that I, EDWIN L; Ronnrrsorn. a citizen of the United States, residing at the city of New York, in the county or New? York and State of New York,y have invented certain new and useful Improvements 1n Rubber Heels, of which the following, taken in connection with .the accompanying drawings,` is a specification.

The" invention relates to heels, for4 boots and shoes; and the improvement consists in providing a metallic cup and crowding a sectional rubber heel; thereinto so that said cup shall retain the same,-V said cu being attached to the boot or shoesole be orethe-r insertion of therubber heel, one of thev sec-` tions of said rubber heel being cylindricalf or having a cylindrical portion so: that itI may be removed fromthe cu andfA said eylindrical portion turned a Vsu cient distance to present a new wearing surfaceattherear of/ said heel ywhere itusually.7 wearsv first to thereby preservea substantially level surface on the bottom of the rubber heel, said rubber heel projectingbelow said metal cup; and the invention consists in the novel ,fea-l tures and combinations hereinafter set forth 'andy claimed.`

heelffwitliin the meter cup, the cylindrical. portion being at the rearin order to turn" the same to present a fresh wearing surface; and Fig. 3 is a botom plan view of the two ,parts of the rubber portion of the heel removed from the metal cup showing the shape of each part; and Fig, 4 is a bottom plan view of the preferred manner of makl ing and vulcanizing the two-part rubber heel, showing in dotted line the cuts to be made in the rubber after vulcanizing, thereby making a pair of rubber heel portions in one piece, the out edges being covered by adjacent parts so as not to expose the same; and Fig. 5 is a plan view of the heel shaped cup showing the openings in the bottom of the same for attachment to the shoe sole.

Like characters of reference refer to corresponding parts in the several views.

The numeral 15 designatesfthe shoe which hS insole t6 to which the-heel L7 is attached preferably by meansnof.r nails 18 lwhich mayv beclenched within said sole 16.

The heel 17 consists ofy a metallic cup 19,1 which' is' preferably shaped in the regular heel form, and` has anopening which enlarges inwardly', that is, towardthe bottomof said cup so as to moreperfectly retain the rubber or elastic portions 20, land 21 of the heely when they are crowded into the cup 19 and more perfectly preserve the heel shape. The cup 19 has a number of openings 22 in the .bottom through4 which the nai-lsl 18 are inserted, inattachingv to the sole 16 of the shoe.` The` sides of the cupi` -19` extend downwardly to within about an eighth or three-sixteenths 0i an' inch of the bottom of the rubber filling parts 204 and 21,- that is, said rubberiilling partsz20=and- 2i extend from. about areighth to' threesixteenths of an inchl below the lower edge of. the metallic cup` 19 se asl to present a strong rubber tread wearing surfaces for the heel without contacting the lower of the cup at each step.

When theheel wears downto the ofv the'cup', the cylindrical r-ubberpontion 201 is removed from the 1f9` imd'turned suffrciently to-ohtain ainewlevel wearing-surface for inidrear or other portionf sincermost wearereof yfoot `gear wear their' rear side: Thisfptesentsl an? entirely surface in placeof said worn side and thus gzmlnellyzean onmenselh greatly pro onging the life of the D In order to rotate the rubber wearing portion of the heel and preserve its shape it must have the round portion yat the rear side. Accordingly said rubber partis referably made as s own in Fig. 4 an cut through the center to form two heels as shown at 25l and having the semicircular cuts 26 to form the round rear portions. The two portions 20 and 21 compress against one another and are suiiiciently large to necessitate crowding into the cup 19 which cu as hereinbefore stated is preferment within said cup though such attachment wo invention. `f "i I It is apparent that this simple and convenient rubber heel may be made vat lo-.W

cost and has great strength and longevity.

The cups may be struck up from sheet I netal by suitable dies. The rubber fillers may be molded and c ut to shape, as shown in Fig. 4,., and the' cups' and' rubber parts may 'be' packed ready for attachment and-l asseml' blage on the shoe sole, I claim as new '-1. `A .cushion boot and shoe heel comprising a heel shaped cup attached invertedto the sole of said'v boot or shoe through the bottom thereof, a rubber filler for said cup composed of acylindrical rear'portion and a portion shaped to fit in the front portion of said cup a'nd around the front section of said rear portion,fsaid filler portions sufficiently larger than. said cup to be compressed thereinto by pressure to hold the same and extending a spaced distance below the same to provide a cushion'tread.

2.. A cushion boot and shoe heel comprising a heel shaped cup Vstruck up from sheet metal having a plurality of holes through the bottom of the same,said cup inverted composed of a cylindrical rear pant and Ia second part shaped to ll the fron-t portion of said cu and tit aroundthe front of said cylindrica rear art toperinibremoval of saidrubbe'r cushion andthe :change of said p cylindrical rear;v part to present a new level'v wearingsurface at the :rear fof Athe heel, and

Inan elastic boot and shoe heel, a cup having a4 semi-circular wall and a straight walhand resilient heel member composed ,ofya main cylindrical part and a filler, the main part fitting against said semi-circular walll and the ller having a concave pontion fittingV against the remainder of the main ipart. and :a straight-y portion itting against the straight wall of the cup.

4. In an elastic boot and 'shoe'heehacompressible` rotatable main member, a compressible non-rotatable filler member abuttingthe main member, and means engaging the outer Walls of each off said members to attach same tov the sole of the boot or shoe.

5. In an elastic boot and shoe heel, a compressible cylindrical member, a compressible filler member, and a cup receiving both of said members.

6. In an elastic boot and shoe heel, a reversible and compressible main member, a compressible-rller member, and means engaging the outer walls ofvfeach of said members to'attach same to the sole of the boot or shoe.

7. In an elastic boot and shoe heel, a re-v versible compressible main member, a compressible filler member and a cup removably receiving both members.

8. In an elastic boot and shoe heel, a cup, and a lsectional heel therein, each of the sections being compressible and meeting in a surface which is approximately normal to the tread vsuri'ace of the heel.

In testimony whereof I have aiixed my signature in the presence of two witnesses.
